In patients with phenylketonuria (PKU) compliant to diet greater tendency to overweight and higher inflammatory biomarkers levels than controls were reported. Although this could lead to atherogenesis, the elastic properties of large arteries in PKU patients have never been assessed. The aim of this study was to assess arterial stiffness measured by applanation tonometry in PKU patients compared to healthy controls.We carried out a cross-sectional study in 41 PKU patients (range age: 6-50 years old) and 41 age- and gender-matched healthy controls...

The progression of chronic kidney disease (CKD) inverts the arterial stiffness gradient. However, central hemodynamic pressure profiles in CKD have not been fully examined. A cross-sectional study was performed to assess the relationship between the CKD stage and central hemodynamic processes. The study enrolled 2020 hypertensive patients who had undergone echocardiography and measurement of their serum creatinine levels. Radial tonometry was applied to all patients to measure central blood pressure. Patients were classified according to six CKD stages based on their estimated glomerular filtration rate...

BACKGROUND: Previous studies have demonstrated that arterial stiffness is associated with lumbar flexibility (LF). Stretching exercise targeted to improve LF may have a beneficial effect on reducing arterial stiffness. OBJECTIVES: We examined the effects of a single bout of a structured, static stretching exercise on arterial stiffness, LF, peripheral and central blood pressure (BP), and heart rate (HR) and tested the association between LF and central arterial stiffness...

BACKGROUND AND AIMS: Severe cardiac load increases circulating concentrations of high-sensitivity cardiac troponin I (hs-cTnI) through non-ischemic mechanisms. The present study was designed to investigate the effect of central blood pressure (BP), which reflects cardiac load rather than peripheral BP, on serum concentrations of hs-cTnI in subjects with or without increased arterial stiffness. METHODS: We enrolled 1210 participants taking part in a yearly health checkup program...

The aim of this study was to elucidate if patients with coronary artery disease (CAD), who fail to respond to revascularization procedures, can improve from individual shear rate therapy (ISRT). The ISRT is an adaptation of the external counterpulsation with lower individual treatment pressures based on Doppler-ultrasound measurements during counterpulsation. In contrast to the external counterpulsation therapy, the ISRT is based on the detection of the individual intra-arterial shear rate. Here we report about the first clinical trial of 31 patients with CAD who were enrolled for 30 sessions of ISRT...

Objectives: Regular exercise is known to reduce arterial stiffness (AS) in hemodialysis patients. However, the impact of a more realistic intradialytic form of exercise, such as pedaling, is unclear. We aimed to examine 1) the effect of intradialytic pedaling exercise on AS over 4 months, and 2) the longer-term effect of pedaling on AS 4 months after exercise cessation. Methods: Patients on stable in-center hemodialysis (3x/week) were randomly assigned 1:1 to either intradialytic pedaling exercise (EX) or to a control group receiving usual hemodialysis (nonEX) for 4 months...

PURPOSE: Recently, cardiovascular risk is thought to be increased in patients with nonfunctioning adrenal incidentaloma (NFAI). There are no sufficient studies in the literature to evaluate this situation in NFAI patients without cardiovascular risk. The objective of this study is to compare peripheral and central blood pressure and arterial stiffness between patients with NFAI and healthy volunteers (of a similar age, gender and body mass index as the NFAI group) who have no traditional cardiovascular risk factors and autonomous cortisol secretion, with pulse wave analysis (PWA)...

BACKGROUND: Pygmies living in the Central African rainforest with a traditional hunter-gatherer lifestyle have a low incidence of cardiovascular diseases. Because of progressive loss of traditional habitat and ancestral lands, some Pygmies have migrated to urban areas and adopt specific Bantu lifestyles such as increased salt consumption and a sedentary way of life. We tested the hypothesis that migrant Pygmies could present with hemodynamic and metabolic characteristics different from those of traditional in-situ Pygmies and possibly closer to those of Bantu farmers...

BACKGROUND: Hypertension is a risk factor for coronary heart disease and stroke, and is one of the leading causes of death. Although over a billion people are affected worldwide, only half of them receive adequate treatment. Current guidelines on antihypertensive treatment recommend combination therapy for patients not responding to monotherapy, but as the number of pills increase, patient compliance tends to decrease. As a result, fixed-dose combination drugs with different antihypertensive agents have been developed and widely used in recent years...

INTRODUCTION: Carnosine, an over-the-counter food supplement, has a promising potential for the prevention and treatment of chronic diseases such as type 2 diabetes (T2DM), cardiovascular and neurodegenerative diseases through its anti-inflammatory, antiglycation, antioxidative and chelating effects. We have previously shown that supplementation with carnosine preserves insulin sensitivity and secretion in non-diabetic overweight and obese individuals. The effect of carnosine on cardiometabolic risk and related cognitive outcomes in patients with pre-diabetes and T2DM has thus far not been studied...

BACKGROUND: Central aortic blood pressures and arterial stiffness are better indicators of cardiovascular outcomes than brachial blood pressures. However, their response to renal denervation (RDN) in patients with stage 3 and stage 4 chronic kidney disease (CKD) has not yet been examined. OBJECTIVE: To evaluate the impact of RDN on central blood pressures, brachial (office and ambulatory) blood pressures, arterial stiffness, glomerular filtration rate (GFR), 24-hour urine protein, and selective cardiac parameters observed on echocardiograms...

High dietary sodium intake can lead to hypertension and increased incidence of cardiovascular disease. We sought to determine the effect of short-term dietary sodium loading on central blood pressure and arterial stiffness in young (YG; 22-40 years) and middle-aged (MA; 41-60 years) normotensive adults. YG (n = 49; age: 27 ± 1 years) and MA (n = 36; age: 52 ± 1 years) subjects were randomized, in a cross-over design, to 7 days of low-sodium (LS; 20 mmol/d) or high-sodium (HS; 300 mmol/d) diet...
